A nicotine soap solution has "been found efficient against 
beetles on willows, and this is also the best contact insecticide 
for aphids and destroys to some extent the moth caterpillars in the 
sho o t s .

Nicotine sulphate can be used with any of the fungicides or 
poisons with perfect safety, but it is more efficient with sodium 
sulphide solutions than with lime-sulphur or bordeaux mixture.

Nicotine was effective, but tobacco powders, containing as much 
as 5.26 percent of nicotine had little or no value on bedbugs and cock- 
roaches. Fumigation with nicotine at the rate of 8 oz. of 40 percent 
nicotine sulphate to 1,000 cu. ft. was ineffective against cockroaches. 
Various tobacco extracts used at reasonable strengths were valueless 
against clothes moths. Nicotine solutions and tobacco powders were of 
no practical value against carpet beetles.

Tobacco dust is recommended in Spain as an effective insecticide 
and preferable to tobacco juice; however, its cost seems to make it 
prohibitive in Spain.
